Abstract

The invention relates to a thermosetting one-component epoxy resin composition comprising at least one liquid epoxy resin A1, at least one liquid epoxy resin A2, at least one curing agent B for epoxy resins, at least one core-shell polymer D1 and at least one terminally blocked polyurethane polymer D2. The weight ratio of the sum of the at least one liquid epoxy resin A1 and the at least one liquid epoxy resin A2 to the sum of the at least one core-shell polymer D1 and the at least one terminally blocked polyurethane polymer D2 ((A1+A2) / (D1+D2)) is from 0.75 - 3. The epoxy resin compositions have good lap shear strength and impact peel values, as well as before and after cataplasm treatment.
